What does car maintenance need to do?

It is not clear what kind of car you are, because the maintenance content of each car may be a little different, so it is impossible to give an accurate answer. But my advice is to refer to the manual and the manufacturer's advice. Because when the manufacturer sets the maintenance project, it will be based on the vehicle design, the local environment and the oil (of course, it will also take into account the after-sales profit), and it is obtained after a long time test and investigation, which is quite valuable for reference.

In addition, some owners will be more concerned about the condition of the car, and will change some accessories in advance that have not yet changed the mileage. Of course, there will be no harm, but there will be no benefit, purely for the 4S shop to create more after-sales output value. Cars and people are the same, people take supplements is good, but eat too many supplements is not necessarily better; Regular maintenance and inspection can keep your car in good condition, but maintenance too often and at every turn 'major maintenance' will not make your car in any better condition.

However, this is only under normal circumstances, because manufacturers can only predict the environment and habits of the car. For example, if the dust in your city is very large, the air filter has been blocked at 20,000 kilometers, you must not refuse to replace the air filter because the manufacturer stipulates that the air filter will be replaced at 30,000 kilometers, so that it will ultimately outweigh the loss. So you can use the manufacturer's recommended maintenance projects, mileage as a reference, but do not ignore the impact of external factors.

The most common reason for deviation is because the tire pressure on both sides is different, the tire deformation on the side of the low pressure is more serious, the resistance will be greater, and it will naturally cause deviation. It's not a fault if the air pressure adjusts and returns to normal.

The same tire pressure does not mean that the problem of the tire is completely eliminated, if the tire wear degree on both sides is significantly different, it will also cause deviation. In the routine maintenance of 4S shops, there will be four-wheel transposition, which is to keep all four tires as evenly worn as possible. In addition, there may be deviation after the replacement of the spare tire, even the full-size spare tire may also cause deviation due to different degrees of wear.

After eliminating the tire problem, let's first see if there is a problem with the four-wheel positioning value. In addition, the aging and loosening of the steering system and chassis components may also lead to deviation. Finally, if the vehicle has been in a collision, it may run off due to slight deformation of the frame. If you exclude the tire problem, it is not very convenient to repair yourself, it is recommended to go to the 4S shop.

The general car is easy to appear small scratches in daily life, this small scratch is generally very troublesome, do not repair and feel that it affects the mood, and the time and money cost of re-painting are relatively high. If the scratch is very shallow and does not hurt the primer, you can buy a can of scratch wax and use a towel to do a simple polishing and waxing; If the scratches are deep, you can buy a paint pen to repair temporarily, although there will be some repair marks after repair, but you can make the scratches less obvious; If you are not satisfied with the effect of this temporary repair, you can wait for a period of time and then re-paint with other scratches, which can greatly shorten the repair time.
